I wanted to share with you a link I came across that goes along well with this series. While it is my intention to train and help in topics and areas for which there is no documentation and coverage, I would never want to reinvent the wheel.
http://edutraining.googleapps.com/Training-Home is a site that will actually take you through the Google Apps mentioned here in more detail.
I hope that this series has served to give you some ideas of how you might actually implement this in the classroom.
Stay tuned for the Google Sites post...
